Subject: [PATCH] gnulib/regcomp: Fix uninitialized token structure
80913e
80913e
The code is assuming that the value of br_token.constraint was
80913e
initialized to zero when it wasn't.
80913e
80913e
While some compilers will ensure that, not all do, so it is better to
80913e
fix this explicitly than leave it to chance.
